Waste management - Import export

Energy production from biomass and waste is on the rise throughout Europe and the world. KROGER has been an established, reliable partner in this sector for many years. KROGER’s maintenance-free grab systems are especially advantageous in both safety and economic terms when used in waste incineration plants, refuse-derived fuel (RDF) incineration plants, combined heat and power (CHP) plants and slag handling. In these extremely difficult, hard-to-access environments, maintenance or lubrication work is costly and often risky for service technicians. KRÖGER offers rrope or motor grabs for a variety of different cranes for use in this particular industry.

Slag handling in waste incineration plants or incineration plants of any kind. For various types of cranes with internal or external holding cables. Technical design Designed as a discharge grab with stable, retracted pivot bearings Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Self-locking grab suspension for crane hooks Grab drive: Vertical electrohydraulic drive unit with high-pressure pump Closing and opening movements are controlled through clockwise or counter clockwise rotation of the electric motor (turn control). The electric motor is only switched on whilst the closing and opening movement is being performed. Closing and opening movements controlled by directly connected hydraulic cylinders, with stable piston rod protection Grab connection bearing Re-greaseable, robust steel bushing bearing KRÖGER MAINTENANCE-FREE bearing system Grab shells: Shell design adapted to material flow Toothed segment drive Material: S355J2+N

Underwater gravel and sand extraction using dredgers with 2-cable or 4-cable winches. Suitable for use in all river and lake dredging areas with difficult ground conditions and deep dredging depths. Technical design MAINTENANCE-FREE design, which benefits both the environment and your profitability High load capacity thanks to its lightweight design Robust, torsion-resistant grab design for maximum loads Grab shells made of wear-resistant fine-grain steel Tooth tips are interchangeable depending on ground conditions KROGER MAINTENANCE-FREE bearing system in the shell pivots and cylinder rod bearings KROGER power unit is easy to service, the crosshead engine is separate from the hydraulic tank, hydraulic units are in the tank Environmentally friendly hydraulic fluid using organic oil

Waste incineration plants, refuse-derived fuel (RDF) incineration plants or incineration plants of any kind. For various types of cranes which operate using hooks or rope/chain suspension. Technical design Open shell design Suitable for handling all kinds of waste Optimisation of crane load capacity thanks to its lightweight design which can hold maximum loads Self-locking grab suspension for crane hooks Grab drive: Vertical electrohydraulic drive unit with high-pressure pump Closing and opening movements are controlled through clockwise or counter clockwise rotation of the electric motor (turn control). The electric motor is only switched on whilst the closing and opening movement is being performed. Closing and opening movements controlled by directly connected hydraulic cylinders, with stable piston rod protection Grab connection bearing: Re-greaseable, robust steel bushing bearing KRÖGER MAINTENANCE-FREE bearing system Stable shell structure with shells made out of S355J2+N

Slag handling in waste incineration plants or incineration plants of any kind. For various types of cranes with internal or external holding ropes. Technical design Low-maintenance or maintenance-free for increased profitability Transverse or longitudinal suspension with 4-fold, 5-fold and 7-fold rope reeving; as a 4-rope grab High load capacity thanks to its lightweight design Smooth grab thanks to its low centre of gravity and because the rope’s diameter matches that of the pulley Closing rope devices: Rope nozzles KROGER MAINTENANCE-FREE, rope-protecting, roller-bearing pulley system Lower pulley block unrestrained on the crossbeam Rope pulley bearing: Re-greaseable plain bearing KROGER MAINTENANCE-FREE pulley block system Grab shells: Material: S355J2+N Cutting edge material: special, highly wear-resistant steel Grab connection bearing: Re-greaseable steel bushing bearing KRÖGER MAINTENANCE-FREE bearing system
